What is life to somebody that is 18 years of age?

They say this time is meant to be the best in your life, the years to remember and the start of a new beginning - but are the cliches really true? Instead of this promise of adulthood and the high expectations of a fun and easy time it appears to be the complete opposite. Individuals are faced with the independence they don’t want and extreme loneliness and stress. The amount of pressure placed on young adults in this generation is far too much resulting in a loss of “the best times.” 

I don’t know whether it is just me but I feel like if these are the best times of our lives, what is the point if all we have to achieve is loneliness and disappointment?
